Moses Gunesch the creator of FuseKit created a very nice open-source tool called TweenBencher. The utility can be used to chart animation performance through the Flash Player’s framerate over the time of the animation. This is a really nice tool and goes a long way to helping developers figure out which animation package to use and for what reasons.

I’ve been playing with all of these, and I’m not sure if the link above is the Simple AS3 Tween or not but it by far is outperforming the others for my situation. I wish there were more options, but its still great. Thanks for the link Jeremy.
